MdNup62 interactions with MdHSFs involved in flowering and heat-stress tolerance in apple.

ABSTRACT: Because of global warming, the apple flowering period is occurring significantly earlier, increasing the probability and degree of freezing injury. Moreover, extreme hot weather has also seriously affected the development of apple industry. Nuclear pore complexes (NPCs) are main channels controlling nucleocytoplasmic transport, but their roles in regulating plant development and stress responses are still unknown. Here, we analysed the components of the apple NPC and found that MdNup62 interacts with MdNup54, forming the central NPC channel. MdNup62 was localized to the nuclear pore, and its expression was significantly up-regulated in 'Nagafu No. 2' tissue-cultured seedlings subjected to heat treatments. To determine MdNup62's function, we obtained MdNup62-overexpressed (OE) Arabidopsis a
